Methodology to Calculate Sight Distance Available to Drivers at Skewed Intersections

Transportation Research Record: Journal of the Transportation Research Board, 2002
A methodology was developed to calculate sight distance available to drivers at skewed intersections of minor roads that are controlled by stop signs. The methodology considers the fact that the sight distance may vary depending on the position of the driver and the different lines of sight given to the driver by different types of vehicles.

Calculating Method and Safety Evaluation of Highway 3D Available Sight Distance

Applied Mechanics and Materials, 2011
Visual information is the basis of highway traffic safety, which is important for a driver to take right actions in driving. From the driving theory and the driver’s sight characteristics, the concept of available sight distance is put forward. According to extend and apply the theory of the spatial intervisibility between two spots, the math model of ...

Analysis of dynamic available passing sight distance near right-turn horizontal curves during overtaking using LiDAR data

Canadian Journal of Civil Engineering, 2020
The purpose of this study is twofold: to construct a model for measuring dynamic available passing sight distance (APSD) during overtaking using light detection and ranging (LiDAR) data, and to investigate the effects of several critical variables on dynamic APSD. The analysis considers a single passed vehicle with several variables, including vehicle

Evaluation of available sight distance estimation method on rural roads according to Croatian regulation

International Conference on Road and Rail Infrastructure
Every driver must have sufficient visibility (sight distance) in front of the vehicle to be able to stop the vehicle in time in front of an obstacle on the road at the posted speed. This means that the available sight distance (ASD) in front of the driver must be greater than or equal to the stopping sight distance (SSD) required to stop the vehicle in

Delineating Sight Occlusions of Head-On Traffic Signboards under Varying Available Sight Distances Using LiDAR Point Clouds

Transportation Research Record: Journal of the Transportation Research Board
It is essential to delineate visual occlusions of head-on traffic signboards under varying available sight distances (ASDs) to improve road safety and guide maintenance. However, the status of sight occlusions in actual road scenarios is unclear because of the lack of an automatic and quantitative evaluation approach.
